Abstract

An impedance matching circuit (14) for a radio receives antenna signals and has its matching elements (56,58,60), such as capacitors, progressively switched into the circuit, with the matching element configuration resulting in the highest RSSI being subsequently used until a succeeding test or antenna impedance change. The effect of the matching circuit (14) is accounted for in the transmitter calibration routine so that the matching circuit works for both half duplex and full duplex.
